Embodiment 1

[0058] 1. Cultivation of root section seedlings of Salvia miltiorrhiza

[0059] (1) Select 300 Danshen seedlings with a fresh weight of 300-400g per plant;

[0060] (2) Intercept the root strips of Salvia miltiorrhiza seedlings, the root length is 4-5cm, and the diameter is 3~8mm, and the root strips intercepted by each Salvia miltiorrhiza seedling are 15~25; figure 1 Shown is a picture of the root strips cut from the seedlings of Salvia miltiorrhiza.

[0061] (3) Pack 8 ± 2cm thick seedling-growing matrix in the foam box, insert the above-mentioned Salvia miltiorrhiza root strip, cover the seedling-growing matrix again on it, and its seedling-growing matrix total thickness is 20 ± 2cm;

[0062] Wherein, the seedling-raising substrate is peat:perlite:vermiculite=1:1:1, and the water content of the seedling-raising substrate is kept at 30-40%;

[0063] (4) Put the above-mentioned foam box (such as figure 2 Shown is the picture that the roots of Salvia miltiorrhiza seedlings...

Abstract

The invention discloses a cultivation method of salvia miltiorrhiza root segment seedlings and a propagation method of salvia miltiorrhiza. The cultivation method of the salvia miltiorrhiza root segment seedlings comprises the following steps: accelerating germination of root strips of a plurality of salvia miltiorrhiza seedlings to obtain the salvia miltiorrhiza root segment seedlings; the fresh weight of each salvia miltiorrhiza offspring seed is 300 g or above; the starting time of germination acceleration is the middle ten days of December; the germination accelerating is carried out in a greenhouse at the temperature of 15-20 DEG C. When the cultivation method for the salvia miltiorrhiza root segment seedlings is adopted for salvia miltiorrhiza propagation, the acre yield can be remarkably increased, and the germplasm of the salvia miltiorrhiza seedlings obtained through planting is neat.

Description

technical field [0001] The invention relates to a method for cultivating root segment seedlings of salvia miltiorrhiza and a method for multiplying salvia miltiorrhiza. Background technique [0002] At present, the cultivation of Salvia miltiorrhiza is mostly propagated by seedlings and root segments. Seedling propagation is the process from sowing the seeds of Salvia miltiorrhiza to digging the seedlings, which lasts about 210 days, and the variation rate of appearance, yield and content of Salvia miltiorrhiza is relatively high. Salvia miltiorrhiza The yield per plant varies greatly, fresh weight is 50g-800g / plant, the variation rate is about 60%, and the average weight per plant is about 200g, and the fresh weight per mu is about 1200kg, which seriously restricts the total output of Salvia miltiorrhiza. The Danshen harvested in the field is used as the propagation material, and the variation rate of the fresh weight of the Danshen is still high, still maintaining a variat...
